Add a simple leak tracer to the IOMMU code. This is useful when you
are debugging a buggy device driver that leaks IOMMU mappings.
-config MMIOTRACE
- bool "Memory mapped IO tracing"
- depends on DEBUG_KERNEL && PCI
- select TRACING
- help
- Mmiotrace traces Memory Mapped I/O access and is meant for
- debugging and reverse engineering. It is called from the ioremap
- implementation and works via page faults. Tracing is disabled by
- default and can be enabled at run-time.

- See Documentation/tracers/mmiotrace.txt.
- If you are not helping to develop drivers, say N.

-config MMIOTRACE_TEST
- tristate "Test module for mmiotrace"
- depends on MMIOTRACE && m
- help
- This is a dumb module for testing mmiotrace. It is very dangerous
- as it will write garbage to IO memory starting at a given address.
- However, it should be safe to use on e.g. unused portion of VRAM.
-
- Say N, unless you absolutely know what you are doing.
